-r METAL WINDOW CONSTRUCTION.

l Application filed. February 1, 1926. Serial No. 85,095. x

The present invention relates to metallic Window constructions, and is particularly concerned with improvements in such parts thereof as the muntin bars, the sashy guides, the cord pulleys7 the weight pockets, and other of the structural elements.r

' One object of the invention is to provide, in a metallic Window construction, an improved muntin bar which is light, strong and durable in character, may be fabricated at small expense with the use of very simple equipment, is capable of being easily glazed,

and requires only a very thin layer of puttyV in the glazing operation.

Another object is toprovide an improved sash guide which is extremely simple in character, will cooperate with both the upper and lower sashes in a double-hung window, and affords an eficient weather' closure for the margins of the sashes when the latter are in closed positions.

Another object is to provide an improved mounting for the cord pulleys, whereby the pulleys are rendered readily accessible for.

replacement, adjustment, or repair.

A further object is rto 'provide an improved closure` for the weight pockets, whereby theweights may be vwithdrawn to permit the removal of worn cords and the attachment ofnew ones.

The foregoing statements are-hutindicative in a general way of the nature ofthe invention, and other objects and advantages connected with various features of the win# dow will be evident to those skilled inthe art'upon a full understanding of the novel construction and arrangement of parts herci-n illustrated and described. 'One form of the invention vis presented for the purpose of exemplification, Y'but it should be understood that the invention is not conned in its practical application to the precise structural details of that form, as such details quite obviously maybe modified in variousurespects withoutdeparting from Within the comprehensive scope oi the invention as defined by the claims.

f The-'metallic window construction illustratedin the drawings is: of the double-hung sash type, as certain, though not all, ofthe features of they invention are particularly applicable to windows of that type.

so A

The frame of the window is: composed-of four permanently connected sheet. metal channel? members 10, 11,; 12 and 13 which members are so arranged ,that the bases of,

the channels thereinV serve to form the inner periphery of ther frame. "TT

e4 sill member 10 'is provided with two i portion 15`is arranged at slight forward ,n

inclination, as is usual inV sill formations.

The lintel member llpis provided with a groove`19 which is positioned with its sides '20 and 21 in the planes of thek upper sash in order toreceive thel edges 22 and 23'k of fthev upper raill 24 of such sash. @ne of the sides Y i of the .groove is preferably set' at a slight angle to the bounding planes of the upper sash so as to obtain a wedging fit. of the rail 24 in.` the groove.' Y n' `Each of the two jamb members 12and 13 is provided with a Vwal-'l portion 25vv against which the front edge 26 ofthe stile-'27 of the upper sash is adapted' to fit. The jamb eX- tends rearwardly from the wall portion 25 in a flat surface. f-

The openings in the channels of the lintel and jamb members are preferably closed ofi.' from the surrounding masonry ot the building in which the window is installed by relatively thin sheet metal strips 28 which' are attached to the edges ot' the members. The opening in the sill member is not closed off, but the memberl may: be provided with a downwardly flanged sheetv metal strip 29 which is adapted to extend into a groove in the sill of the supporting masonry, where it serves as a water bar. y

Therails and stiles of the upper and lower sashes are of hollow sheet metal formation, and the margins of the glass panes 30 extend into relatively small putty grooves which are formed in the rails and stilesl by U-shaped strips 3l which are lixedly positioned therein.V The' strips 3lv in the top rails may be of greater vertical extent than those in the bottom rails in: order that, when the sashes are being glazed, the glass panes 30 may be raised-upwardly in the upper grooves aV suiicient distance to permit the lower margins of the panes to first-.clear Vthe upper margins of the kbottom rails and then seat in the grooves therein, which arrangement makes possible a permanent .assemblage ot the structural elements constituting the rails and stiles. l Y Y In'the lower sash, the bottom raillS-is composed of two parallel side strips 32 which are held in fixed relation by two con- The associated glass-retaining strip 31 is anchored to the'uppermost strip 33,I and the upper margins of the side strips-32 are curvedv vtoward each other over the edges ot the strip 3l'. The top rail 34 is composedfof two parallel side-strips 35 which are perpendicularly flanged inion'e direction and securedtogether in front of the sash at36, one of the flanged portions being provided in 'front of the sash with a downwardly extending flange 37- which is adapted, when both the upper and lower sashes are in closed positions, to imbedin a weather strip 38 ot felt or other suitable material carried vin a groove `formed in the bottom rail 39 of the other sash. The stiles 40 are quite similar-in construction to the bottom rail 18, the principal differences beingthat the sideV strips 41 are of equal instead ot' unequal Width, and-'that but one connecting strip 33 is used between the side strips-owing to the fact that the stiles are` less elongated in cross section than .therail s In the upper sash, the bottom rail 39 is composed of a front'side strip 42 which is iianged'rearwardly atl its-lower margin and ,then upwardly to form the rear side of the groove 'in which the weather strip 38 is located, and a rear side strip43 which'is secured to the strip 39 in such a way as to form asmall putty groove for the lower mar.- gin of the glass pane 30 and a relatively largehollow box rail extending rearwardly7 from the putty groove to a point closely adjacent the front flange 37 on the top rail 34 of the lower-sash. The top rail 24 is composed of two parallel side strips 44 which are held in ixed relation by a connecting strip 45 which also serves to reinforce the upper edges 22 and 23 of the rail. The stiles 46 are substantially the same in construction as the stiles 27 of the lower sash.

Each ofthe muntin bars 47 ot' the sashes is composed of twochannel strips 48 ot curved cross section, one of the strips being fixedly connected at its ends withv the associated rails, and the other being detachably secured to the fixed strip.l The channel in the vtixe'd strip is closedat a point just inwardly of itsedges with a flat strip 49 from which tongues 5() are punched out at intervals and seatl against the back ot' the strip, where they are welded in position'. The channel in the detachable strip is also closed in the same manner, but the strip 51 used may be of considerably thinnerr gauge. The detachable strip is secured to theixed strip by means or' screws 52 which extend through apertures in the strips 48 and 51 and engage in screwthreaded apertures in the strip `49..The construction described is light, Visfstrong, may be easily produced, and requires but a very thin layer rot putty between the glass Y and the strips 49 and 50 in the glazing operai plane of the lower sash. The strips are of a triple channel formation in which relatively wide middle channels` 55 face toward the jambs and relatively narrow side channels 56 face toward the openings in such channels,.and are sufficiently resilient tobear with spring pressure against the edges of the sashes which the channels 56 are adapted to receive. The rear edges 'ot' the stiles 46 of the upper sash are guided in the front side channels56 of the guide strips, and the front edges ot' the stiles 4l of the, lower sash are guided in the rear side channels. The back portions of the middle channelsv 55 'in the guidek strips are slightly concave toward the sashes, which construction eliminates the necessity of counter-sinking the attaching screws 54 in the metal of the strips. At that point where the top rail 34 of the lower sash is positioned alongside the bottom railV 39 of the upper sash when both vsashes are in closed position, a boss 57 is formed on the back-.of the middle channel ineach of the guide strips by the elimination at that point of the concave formation described, and such.

boss fits closely againstthe ends 58 of those i portions of the rails 84 and 39 which extend toward each other in hooked'` relation be- Y positioned in the upperends of the reark side channels 56 in the guide strips The lower` front edge of the bottom rail 18 out" the lower Sash is wedged closely against the wall portionzlot-the sill when the sash 1s in its closedl posit-ion, thewedging action being eEeclt-edby notching'thekk lower ends of the guidelstrips at 60as shown in Fig. 6, and

:placing the strips in slightly lapped ,relation: to thewall portion 15'l so as to Vpresent con'stricted but resiliently yieldable 'guide v grooves 61 at those points in the strips adja-l wcent they sill. A. wedge block 62 may also be; used at` a point onthe-'sill intermediate the guide ,strips to supplement the wedging action of the lower ends of such strips.` f he l guide construction above described is claimed yfin my' copendinigfapplication, Serial No.

The pulleys 63 over which the weight cords for the sashes are trained are positioned in the upper corners of the hollow frame,

and are journaled in supporting brackets 64.

The brackets 64 are flattened on one face, and are arranged in small apertures 65 cut 1n the jambs 12 at the corners with the flattened Vfaces of the brackets flush with the faces of the jambs. lThe Vpulleys and brackets are.

arranged in pairs in the corners of the frame, and the two brackets of each pair are secured with screws 66 to a common backing plate 67.l The plate 67 extends below the brackets 64, and is attached by screws 68 to the jamb 12. The upper end of the plate 67 is provided with an angle Vmember 69 which seats in the base of the channel in the lintel member 11 and is attached thereto by a screw 70. The pulley mounting described properly positions the pulleys, and renders them easily removable. If it is desired for any reason to replace one of the pulleys, the screw 70 is withdrawn, vthe screw 68 is loosened to permit the plate 67 with the pulley brackets 64 thereon vto tilt back into the cavity, the pulley is held while the screw 66 is removed, and the pulley and bracket, be-

ing detached from the plate, are withdrawn through the enlarged opening made when the plate 67 was tilted back. A new pulley is then substituted, the backing plate 67k is drawn up into place with the screw 68, and the screw 70 is inserted.
